Abstract

Abstract: Based on the gray system theory , the road traffic safety and the treatment methods of road traffic accidents were researched and explored. The regional road traffic was taken as a gray system; the related inf1uence factors of road safety were taken as the ser:ial number and lhe accident level was taken as the decision attribute. The impact degree of each attribute on road traffic safety was analyzed by the gray correlation degree and entropy numer:ical processing method , from the 0- verall connection degree distr:ibution figure of each attribute' s value and gray comprehensive relational entropy. The proposed method provides decision-making basis for the road traffic safety plan and the treatment of traffic safety

Key words: grey system theory;grey relational degree, gray comprehensive relational entropy, traffic safety analysis

摘要： 基于灰色系统理论研究道路交通安全，探寻道路交通事故的处理方法。将区域性道路交通视为一个灰色系统，道路交通安全的相关影响因素作为序列号，事故等级作为决策属性，运用灰色关联度及其惰的数值处理方法，从各属性的属性值综合关联度分布图和灰色综合关联度恼分析出各属性对道路交通安全的影响程度，为道路交通规划及交通安全治理提供决策依据。
